Question

The answer to this equation no steps needed for me just needed a,b,c or d

Answer 1

- The solution steps are given below:

`\begin{gathered} y\propto(1)/(x^2) \\ \\ \therefore y=(k)/(x^2) \\ where,\text{ }k\text{ is the constant of proportionality} \\ \\ when\text{ }x=1,y=(7)/(4) \\ \\ (7)/(4)=(k)/(1^2) \\ \\ \therefore k=(7)/(4) \\ \\ \text{ Thus, we can say} \\ y=(7)/(4x^2) \\ \\ \text{ Thus, when }x=3,\text{ we have:} \\ y=(7)/(4(3^2)) \\ \\ y=(7)/(4*9) \\ \\ \therefore y=(7)/(36) \end{gathered}`

Final Answer

The answer is

`y=(7)/(4x^2);y(3)=(7)/(36)\text{ \lparen OPTION C\rparen}`
